6 mmdblookup - a utility to look up an IP address in a MaxMind DB file
7
9 mmdblookup --file [FILE PATH] --ip [IP ADDRESS] [DATA PATH]
10
12 mmdblookup looks up an IP address in the specified MaxMind DB file.
13 The record for the IP address is displayed in a JSON-like structure
14 with type annotations.
15
16 If an IP's data entry resolves to a map or array, you can provide a
17 lookup path to only show part of that data.
18
19 For example, given a JSON structure like this:
20
21
22 {
23 "names": {
24 "en": "Germany",
25 "de": "Deutschland"
26 },
27 "cities": [ "Berlin", "Frankfurt" ]
28 }
29
30 You could look up just the English name by calling mmdblookup with a
31 lookup path of:
32
33
34 mmdblookup --file ... --ip ... names en
35
36 Or you could look up the second city in the list with:
37
38
39 mmdblookup --file ... --ip ... cities 1
40
41 Array numbering begins with zero (0).
42
43 If you do not provide a path to lookup, all of the information for a
44 given IP will be shown.
